An electrical connector includes a housing and electrical contacts held by the housing. The electrical contacts include contact beams having wire interfaces configured to engage in physical contact with corresponding electrical wires. The contact beams are movable between closed positions and open positions. The wire interface of each contact beam is configured to engage in physical contact with the corresponding electrical wire when the contact beam is in the closed position. The wire interface of each contact beam is configured to be disengaged from physical contact with the corresponding electrical wire when the contact beam is in the open position. A release member is movably held by the housing such that movement of the release member is configured to move a plurality of the contact beams from the closed positions to the open positions thereof and thereby release a plurality of the electrical wires from the corresponding electrical contacts.
